Final answer:
The code not used when setting priorities is 'Designate'. Effective time management in tasks such as engineering projects requires prioritizing based on urgency and importance, and includes practices like managing email time and separating work from personal life.
Step-by-step explanation:
When setting priorities for effective time management, the code that you would NOT use is C. Designate. The commonly accepted codes when prioritizing tasks are to Do, Delegate, or Delay. 'Designate' is not a standard term used in this context. Prioritizing involves assessing tasks based on urgency and importance, deciding which tasks need to be done immediately, which can be assigned to others, and which can be postponed. For instance, in engineering projects, it is crucial to meet task deadlines to prevent revenue loss or project cancellation, as missing the deadline for the design, testing, and manufacture of a new video game controller may result in missing the profitable holiday season or allow a competitor to capture the market first.
Good time management also includes tips such as setting your priorities at the end of each day, being realistic about achievable goals, limiting email responses to specific times to avoid distractions, and making a distinction between work and private life by turning off electronic communications during your off hours.
